Antioxidant 8608 Application scenarios
1. 플라스틱 및 폴리머
· General-purpose plastics: PVC, PE, PP, PS, etc.
· Engineering plastics: Polyamide (Nylon), Polycarbonate, ABS.
· Elastomers: TPU, CPU.
Provides processing thermal stability, prevents discoloration (yellowing) at high temperatures, and maintains product transparency. Often used as a secondary antioxidant in combination with hindered phenolic primary antioxidants to produce a synergistic effect and improve overall antioxidant performance.
2. Resins and Synthetic Materials
Polyurethane (PU), (un)saturated resins, polyester polyols, coatings.
Protects the color and transparency of polymers during resin synthesis and subsequent processing, and improves the long-term thermal stability of the final product.
3. Other Specialized Applications
Food contact packaging materials, lubricants.
Used as an environmentally friendly alternative (e.g., replacing traditional antioxidants such as TNPP) in applications requiring high safety and transparency.
💡 Core Characteristics and Usage Notes
Core Characteristics: Its outstanding advantages lie in its environmental friendliness (free of phenol, nonylphenol, BHT, etc.), high efficiency (high phosphorus content, strong ability to decompose hydrogen peroxide), and excellent color stability and hydrolysis resistance.
Usage Recommendations:
시너지 사용: As a co-antioxidant, it is strongly recommended to use it in combination with hindered phenolic primary antioxidants (such as antioxidants 1010, 1076, etc.) and UV absorbers to achieve a synergistic antioxidant and anti-photoaging effect of “1+1>2”.
권장 복용량: Typically between 0.1% and 2.0% of the total material weight.
Safe Storage: The product is a liquid and should be stored in a dry, dark, and well-ventilated place below 25°C, away from fire and oxidizing/reducing agents.
In summary, CAS 26544-27-4 is a widely used and high-performance co-antioxidant, especially suitable for polymer materials with high requirements for color, transparency, and environmental friendliness.
